A Brazilian public prosecutor accused two U.S. pilots and four air traffic controllers of contributing to a mid-air collision last year that killed 154 people. The two Legacy pilots, who surived the collision were accused of flying at the wrong altitude. They also inadvertently deactivated the transponder, according to his report. The prosecutor also accused four air traffic controllers of giving incomplete flight instructions and failing to try different frequencies when radio communication with the Legacy jet failed. A federal judge will decide whether to formally indict the six men and open a trial. (Reuters)
